Title: Automatic correlation of points in two separate images
IPC: G06T5/00
Filed: 1970-12-07
Abstract: 1339027 Pattern recognition WESTING- HOUSE ELECTRIC CORP 7 Dec 1970 [31 Dec 1969] 57977/70 Heading G4R A pattern recognition system includes a computer arranged to determine the correlation between two images. The computer selects from both images points which convey the greatest amount of information relevant to the correlation process. The image points are used to provide measurements of characteristics of the images which are invariant, irrespective of the orientation and scale of the images. The invariant measurements of the respective images are compared, and if there is sufficient correspondence between them the image points are correlated. The images to be compared with one another may be photographs, radar plots &c., and may have been derived by sensors responsive to differing radiation frequency bands, e.g. optical and infra-red. A scanner scans one image and feeds a digitizer connected to a unit which determines points of substantial information content. Such points may, for example, be where two or more lines intersect. Colour or grey scale gradients may also define the points. The points are now examined in pairs to determine the orientation of lines emanating from the points relative to an imaginary line joining them, the orientations being the invariant values. The distance between the points of each pair is measured. The invariant values are compared with those obtained from another image, and if there is a sufficiently high degree of correspondence the images are normalized with respect to their scale and orientation. Comparison of the normalized values provides an indication of the degree of correlation of the two images.

Abstract: 1,242,859. Transistor amplifying circuits. RCA CORPORATION. 11 Dec., 1968 [11 Dec., 1967], No. 58806/68. Heading H3T. An amplifying circuit comprises a field effect transistor with a first gate electrode 16 for connection to a source of input signals and a second gate electrode 18 for connection to a gain controlling potential, impedance means, i.e. resistor 40, connected to the source electrode and in series with the source to drain path and a biasing arrangement interconnecting the first and second gate electrodes which causes the potential of the first gate electrode relative to the potential of the source electrode to change in a polarity direction opposite to a change in potential of the second gate electrode relative to the potential of the source electrode. As shown, the first gate electrode derives a fixed bias from potentiometer 32, 34 and a variable bias from that applied to the second gate electrode via resistor 30. A resistor 52 which may be omitted (Fig. 2, not shown) applies a fixed bias to the second gate electrode. The arrangement is intended to bias the first gate electrode so as to minimize cross-modulation as the gain control bias is varied.

Title: Scanning circuitry for a radar plan-position indicator
IPC: G01S7/12
Filed: 1971-12-17
Abstract: 1355228 Cathode-ray tube circuits; radar NIPKIRE 17 Dec 1971 [18 Dec 1970] 58815/71 Headings H4D and H4T A scanning circuit for a radar plan-position indicator (P.P.I.) employs two sine-cosine rotary transformers 2, 4 (Fig. 2) the primary P1 of transformer 2 being rotated in synchronism with the rotation of a radar antenna to produce, when energized, a radial line rotating about a predetermined point on the display cathode-ray tube whilst the primary P2 of transformer 4 when energized produces a reference (marker) line which radiates from the predetermined point and rotates about this point by an amount determined by manual rotation of P2. The primaries are energized by supplying, to input circuit 1 (transistor T1 &c.) a pulse train in which every Nth pulse is suppressed and to input circuit 3 (transistor T2 &c.) a similar pulse train in which every pulse except every Nth pulse is suppressed, the inputs circuits 1 and 3 operating to prevent the pulses supplied to either input circuit affecting the primary winding associated with the other input circuit. In operation, the application of a positive rectangular pulse at the base of either transistor T1 or T2 causes the latter to conduct and saturate so that a linearly rising current flows from the point held at a potential +E, through the diodes D5 to D12, primary P1 or P2 and one of the resistors R3 or R4 to earth. Voltages are thus induced in the secondaries C11, C12 or C21, C22 the magnitudes of which depend on the relative angular position of the primaries with respect to the associated secondaries and cause linearly rising currents to flow in deflections coils L2 and L4 (secondaries C11 or C21) and deflections coils L1 and L3 (secondaries C12 or C22) to produce the required beam deflection. The circuit 6 including the diodes D5 to D12 operates to ensure that the trace produced by the two transformers commences at the same point the position of which may be adjusted by means of adjustable amplifiers 8 and 9 which supply signals to orthogonal deflection coils L6, L8 and L5, L7. The latter coils may be wound in the same slots on the yoke as the coils L2, L4 and L1, L3 respectively and to prevent the comparatively low A.C. impedances of the amplifiers 8, 9 from loading the latter coils chokes Dhl and Dh2 are connected in series with the amplifiers.

Abstract: 1,199,740. Purifying hydrocarbons. UNIVERSAL OIL PRODUCTS CO. 28 Dec., 1967 [30 Dec., 1966], No. 58818/67. Heading C5E. A process for separating a mixed-phase hydrocarbonaceous conversion product effluent containing hydrocarbons boiling above 566‹ C. comprises the steps of (a) separating said effluent in a first separation zone at a temperature above 371‹ C. and a pressure above 68 atmospheres gauge to provide a first vapour phase and a first liquid phase; (b) cooling said first vapour phase, introducing the same into a second separation zone at a temperature below 60‹ C. and a pressure substantially the same as in said first separation zone, and separating therein a hydrogen-rich second vapour phase and a second liquid phase principally comprising propane and heavier normally liquid hydrocarbons; (c) introducing at least a portion of said first liquid phase, at a pressure less than 13À6 atmospheres gauge, into a third separation zone at a point below a mesh blanket which extends across an upper section of said third separation zone, and therein separating a third vapour phase and third liquid phase containing hydrocarbons boiling above 566‹ C.; (d) introducing said third liquid phase into a fourth separation zone at a temperature above 371‹ C. and at a sub-atmospheric pressure and therein separating a residuum fraction containing hydrocarbons boiling above 566‹ C., and a heavy gas oil fraction boiling below 566‹ C.; and (e) introducing a portion of said heavy gas oil fraction into said third separation zone at a point above said mesh blanket. The mesh blanket serves to prevent the entrainment of asphalts in the third vapour phase, the heavy gas oil wash removing the entrapped asphalts from the blanket. The process is particularly applicable to black oil conversion products. The second liquid phase and the cooled third vapour phase may be combined to form a product stream containing more than 60% of butanes and heavier hydrocarbons. Apart from that part of the heavy vacuum gas oil which is not recycled, the products from the final separation stage may also include a light vacuum gas oil.

Filed: 1969-12-18
Abstract: 1293608 Automatic focusing EASTMAN KODAK CO 18 Dec 1969 [23 Dec 1968] 61760/69 Heading H4D In a focusing system for a camera, light from a subject is directed along first and second parallel paths to separate photo-cells, the first path including a modulator and the second, unmodulated, path having its light transmission reduced to the mean of that in the first path so that decrease in the opposed outputs of the two photo-cells stops focus adjustment at the position of focus. In Fig. 1, light from a selected area of a subject to be cine photographed passes through the main camera lens, or, as shown, an auxiliary lens 14 to influence two photo-diodes 18, 24 by virtue of a beam splitter 16. The light falling on photo-cell24 is modulated by a disc 22 having alternate transparent and opaque sectors while a neutral density filter 20 is arranged to balance the output of photo-cell 18 to the average output of photo-cell 24. Focusing is initiated by starting an electric motor 40, Fig. 2, which adjusts the main zoom lens 10 from near focus towards infinity. The modulated output from the differentially connected photo-cells 18, 24 is applied through a band-pass amplifier 30, which eliminates the effects of ambient lighting variations, to one integrating circuit 34 which retains the peak value of the modulation and another integrating circuit 36 which follows the envelope of modulation amplitude as the focus changes. When the peak value reaches a  maximum and the signal from integrator 36 begins to fall relative to the signal from integrator 34, a transistor comparator 38 produces an output to stop motor 40 at the desired position of focus.
